Sample MCG 3100 firewall configuration

If a user calls a client, the SIP signaling comes through the SPS. Real

Time Protocol (RTP) for announcements or MC 3100 Instant Conference

calls takes place between the MCG 3100 and the IP telephone without

using the SPS.

To allow public internet traffic to reach the MCG 3100 from clients, while

simultaneously providing MCG 3100 access to the ECS TLAN for SIP

and RTP, you must carefully consider the data network and security

requirements of the Enterprise.

Proprietary communication between the MCG 3100 and the MCC 3100 for

BlackBerry (without the BES, using HTTP), the MCC 3100 for Nokia (using

HTTPS), and the MCC 3100 for Windows Mobile (using HTTPS) enables

clients to initiate and modify calls for the user on the ECS. In the BES

configuration, the MCC 3100 for BlackBerry communicates with the BES,

which communicates with the MCG 3100. The MCC 3100 for Nokia and

MCC 3100 for Windows Mobile communicates directly with the MCG 3100,

as well as the MCC 3100 for BlackBerry when configured without the BES.

Access to user records in an active directory server configured against the

MCG 3100 uses a tunnel over HTTP or HTTPS. Configure the MCG 3100

to specify the query search base, which limits the search to a subtree of

the base.
